I had already done that check.
Consider we take pictures with an Iphone X so every image is originally about 3 or 4 MB,
once reduced it shrinks down to 300 or 400 KB, which is under the forum limit of 500KB but is still a lot.
This is where our MB have gone.
Recently we have reduced to 640X480 the resolution and reduced the quality of JPEG to 70%,
we use PhotoScape, and we have obtained images of 75 KB each.
I was hoping to get more space, but since this is not possible we will do two things,
firstly we will try to reduce the first images posted, this should free up some space,
then we will use a hosting service, and this should give us more space.
